Gordon has a small square cemented surface just outside his sliding glass door with the a 3ft by 3ft dimension. He wants to enlarge this surface cement patio. He designs by adding 2 feet to the side length of the existing cement surface, and then multiplying this by 4. What all expression would represent the area of Gordon's new patio.

2.83941151 would be the answer you're looking for! : )

to find the unit price of an object, you divide the price by object. you are trying to find out how much an object cost per unit.

for instance, lets say you have 50lb of ice cream(object) that cost 8.00 dollars(price). to find the unit cost, we take the 8.00 and divide it by 50, which will give us .16 cents per pound. we can check this by multiplying .16 by 50 = 8.00

so

object = e2

price = d2

unit price = c2

formula for c2:

=d2 / e2

so in my example about ice cream, we would have the following.

e2 = 50

d2 = 8.00

c2 formula:

=d2 / e2
